Introduction
This chapter provides a description of ISDB‑T Single Frequency Network (SFN) setup and measurement for signal power and signal analysis with Option 32 on the instrument. Note that Option 9 (IQ Demodulation Hardware) may be required in your instrument in order to use Option 32. You can measure channel power along with the field strength and power of each incoming signal even when there are several incoming multi-path signals. The measurement time for delay profile measurements is longer to allow for the measurement of signals coming from distant sites in the network.
Field Strength Measurements in SFN Environments include Level, Delay, and DU Ratio of each incoming signal along with the time delay between signals.
